The 2017 Porsche Panamera 4S has 4 recalls, the most serious involving a coolant pump for the climate control system that can allow moisture inside, cause an electrical short, and start a fire.
On the handling and chassis side, two recalls address loss of control risks. A fault in the rear suspension can cause an unexpected shift in how the vehicle handles, reducing the driver's ability to steer predictably. The electric power steering system can also intermittently drop its assist without warning, which causes the steering wheel to suddenly become much harder to turn, particularly at low speeds where the effort increase is most pronounced and the driver is least prepared for it. There is also a brake concern: the wear indicator for the brake pads can fail to alert the driver when the pads are depleted, leaving metal grinding on metal and significantly reducing stopping power without the driver knowing the pads need replacement.
